Application filed June is, ioni- Serial naeeese To all whom it mayconcern:

Be it known that I, HENBIK C. Strains, a'citizen of the United States,and a resident of the town of Harvey, in the county of (lock and Stateof Illinois, have invented certain new and useful Improvements inInwherein noise and vibration are practically v obviated, and all of theworking parts are positively driven and operate independently ofsp'rings. A.t the present time the most general type of internalcombustion engine ,is'that employing puppet valves, and these areobjectionable for many reasons, not least among which maybe mentionedthe noise accompanyingtheir operation, as well as the inefilcientclosing of the respective passages which they control. In the presentinvention i'clle use of peculiarly efiicient slow moving inlet andexhaust sleeve valves admits a construction employing a small clearancespace, thus makinghigh compressions easily obtainable, and insuring aneconomy of fuel. Another objection to the puppet valve type of motor isthat the valve area is relatively small, and further the opening andclosing movements of the valves and the admission. of the working fluidare not as rapid as desirable, particularly at high speeds. Theconstruction of my engine has made feasible a most convenientarrangement or parts so that the various mecha 'nisms are instantlyaccessible.

it is an object of this invention to provide 'a construction afiordingan operator an opportunity to instantly examine the operating gearwithout the necessity of exploring the crank pit as in case of greatemergency when used in the air, on land at sea.

It is also an object of this invention to construct an internalcombustion engine wherein inlet and exhaust ports are provided attheupper'end of caches" the cylinders thereof and are controlled. bymeans'oit s-ieeves slidahly mounted within said cylin- Spccification ofLetters Patent.

It is also an object of this invention to nective inlet andexhaustsleeves enema Jury it), 3191? construct an internal combustionsleeve valve engine wherein each of the respective sleeves are slidablymounted within theengine cyl- I inders independently of one another andthe engine piston, so that wear, between the re spective sleeves and thepiston is obviated.

It is also an object of this invention to v construct an 1nternalcombustion engine p r'o vention to construct an internal combustionsleeve. valve engine wherein an improved oiling mechanism is providedfor introduc in oil around the sleeve valves.

It is also an object of this invention to construct an internalcombustion engine pro vided with .sleeve valves operatingindependentlyof, and out of contact with, one another by means of valve rods, oneslidable.

It is also an object of this invention to construct an internalcombustion engine wherein sleeve valves are mounted to control therespective inlet and outlet ports at" the upper ends of the cylinders30?? the e21 glue, and with water jackets disposed around the cylindersalso surrounding the,

respective inlet and exhaust ports acting to maintain practically allparts of the engine at a constant temperature. 1

It is also an object of this invention to construct an internalcombustion engine wherein independent sleeve valves are mounted tocontrol the respective inlet and exhaust ports at the upper ends of eachof the i cylinders, each of said sleeve valves being provided with acentral actuatingfrodgtheh y will rod of one valve extending throughthat the other, andeach of said rods operated fromsuitablecneans. v

It isa further object of this invention to construct an improved type ofinternal comhustlon engine. wherein the inlet and ezo haust portscommunicate directly-through the walls of the engine cylinders and. are

controlled by independently movable sleeve valves operating out ofcontact with one another and the piston in thecylinder.

It is finally an object of this invention to construct an internalcombustion engine wherein noise is almost entirely obviated and economyin operation is secured, due to the use of sleeve valves mounteddirectly in the heads of the ei'igine cylinders in a manner permitting asmall clearance space. to be attained.

As shown in the drawings;

The engine'embraces a crank Ease 1, t-he lower portion'Q, of which isremovably bolted thereto, and with hearing members 3.

integrally connected by means of webs at, to the walls of the upperportion 1, of the crank case. Thecylinders in the present instancedenoted by the reference characters A. B. and .l), are preferably casten. 72100 for compactness, although not necessarily so, and around thewalls 5. of each of the cylinders, the casting is cored to afford awater jacket 6, which extends around and over the upper portion of thecylinders. A crank shaft 7, is journaled in the bearings in said crankcase, and 'is suitably connected by means of'connecting rods 8, to trunkpistons 9, one mounted in each of the respective cylinders of theengine.

Inlet and exhaust ports, denoted respectively by the reference numerals10 and 11,

ing with the inlet ports 10, of a cylinder,

and the latter-with the exhaust ports 11, thereof. On each of thecylinders of the engine an inlet 14, is formed through the wall 6. ofthe water jacket communicating with the annular inlet fuel passage 12,andsimilarly an outlet 15. is formed through the opposite all of thewater jacket communi eating with the exhaust passage 13. An intakemanifold 16, is suitably connected upon the outer walls 6, of the enginewith the respective outlets from the manifold registering with theinlets 14, leading to the inlet passages of the cylinders. Similarly anexhaust manifold .17, is mounted on the opposite side of the engine, therespective inlets to the manifold communicating and registering with theoutlet apertures 15, from the exhaust passages of the engine.

The firing of a charge of fuel introduced into-the cylinders is effectedby means of a spark plug 18, threaded into and through the top wall ofeach of the cylinders and at one. side thereof. The valve memberscontrolling the respective inlet ports 10, and exhaust ports 11. in eachof the cylinders, are independent of one another and each similarlyconstructed, the inlet valve consisting of a ring 19. integral with ahollow hub 20, and connected thereto by hollow radial arms 21. whichcon'nnunicate into the hollow hub 20, to receive o-il therefrom and passthe same to the outer periphery of the ring. A

piston ring or packing 22, is recessed into. the outer peripheralsurface of the. valve ring to insure a sealing fit thereof over theinletports 10.

A tuluilarvalve'. rod 23, is integrally connected on the hub portion 20,of the valve and extends upwardly through the upper wall of the enginethrough a suitable packing gland 24. An oil passage is formed within thewalls of said tubular valve rod,

said passage at its lower'end communicating laterally with a passage ina cross head 26,

secured on the upper end of the valve rod and supporting an oil cup 27,thereon in a n'ianner to feed oil into the oil passage.

The valve for the exhaust ports 11, is

similarly constructed, and is denoted as a whole by the referencenumeral 28. In the latter instance, however, the tubular valve messes iextension 31, which supports an oil cup 32,

the oil from said cup passing through a suitable interior, passage insaid arm 31, to the tubular valve rod 29, where it then flows downwardlyand into the valve 28: Of

course, any conventional type of 'check valves may be mounted in the oillines of each of the valves to prevent a reverse fiow' taking placetherethrough, but for convenience of illustration such valves have not?been shown. A gudgeon pin 33, extends through said cross head. 30, andserves to pivotally connect thereto the pair of links 34, which, attheir upper ends, are connected by means of another gudgeon pin 35, toone arm 36, of a bell crank.

A number of supporting brackets 37 two on each cylinder, are mountedon'the upper or top wall of the engine, and extending therethrough is ashaft 38, on which said bell cranks for operating the exhaust valves ofthe cylinders are pivoted.

A cam shaft 39, journaled in bearings at each of its ends,'is positionedslightly below at one side and parallel to said shaft 38,

above the cylinders of the engine, and is suitably driven from the crankshaft '2', by means of'a chain or link belt 40. A housing 41, isprovided to inclose the cam shaft driving mechanisms to'protect the samefrom dust and to deaden the noise of operation thereof.

.A pluralityyoi cams 42, are rigidly secured upon said cam shaft 39, onecam for each' cylinder of the engine, each running in a bath of oil,and, as clearly shown in Fig. 10, each of said cams is provided withcontinuous grooves or slots 43 and 44, respectively, on opposite facesthereof, the groove 43, being for the inlet valve, and the groove44,,for the exhaust valve. Accordingly, in order to operate the exhaustvalve, said hell crank,-having the arm is provided with another'arm 45,which, at its ends has a roller which engages in the groove 44, of

the cam.. Said cross head 26, on the "valve rod for the inlet valve, isprovided with gudgeon extensions 46, upon "which are pivotally engageda'pair of links 47, which, at their upper ends, are connected to one arm48, of a bell crank by means of a pin 49. Said bell crank is alsopivot-ally mounted upon said shaft 38, alongside of the hell crank forthe exhaust valve, and is provided. with another, arm 50, which,'at itsend, is provided with a roller tracking in the groove 43, of the cam.Fig.1, the annular outlet passages for each= As clearly shown in of thecylinders are larger than the annular inlet passages 13, and this, ofcourse, is to permit ready egress of the burnt gases with as little backpressure as possible. The operation is as follows: The cam shaft:39, isdriven by a one to two drive from the crank shaft 7, of the engine, so,that the number of reciprocations of the respective annular inlet andexhaust valves Within the cylinders are only half as great as that ofthe pistons. Of course the respective cam grooves 43 and 4.4:, in thecams 42, are formed so as to open and close the respective inlet andexhaust ports I of the cylinders to insure the proper cycle exhaustpassages cored around the cylin ders within the water'jacket thereof,insures an even temperature of all the Work ing parts of the engine, apre-heating of the inflowing fuel, and a cooling of the exhaust. Qhevalve gearing mounted on the top of the. engine, is of course duplicatedfor each of the cylinders, and as a whole is a very simple mechanism,and dueto the fact that an oil supply is carried upon the respectiveparts of the inlet valve and exhaust valve gearing, a positive oil feeddirectly to the walls of the cylinders of the engine for the valves isinsured. In order to inclose said valve mechanisms from dust and todeaden what little noise of operation there is in this portion of themechanism, a large cover 51, is connected by means-of hinges 52,.to thetop wall of the 'engine and closes over all of said valve gearing, andwhen access to any part thereof. is desired, said cover may be easilyswung back:

Dueto the fact that I use cams provided with cam grooves, the actuatingmechanisms for the respective valves are positively I moved orreciprocated ,111 both directions, thus obviating the use of springs,and inasmuch as the extent or amplitude of move vention which may bevaried through a wide range Without departing from the principlesthereof. I therefore do not purpose limiting the patent grantedotherwise than necessitated by the prior art.
